Specification of Letters Patent.

Original application filed December 5, 1908, Serial No. 466,097. Divided and this application filed November To all whom it may concern:

Be it known that I, GAVIN CARLYLE RAL- STON, a subject of the King of Great Britain, residing at Cleveland, Leyland Road, Lee, in the county of Kent, England, have in vented new and useful Improvements in Apparatus for Discharging Ashes, Ballast- VVater, Bilgeater, and other Materials from Ships and other Places, and is a division of my United States application, Serial No. 466,097, filed December 5, 1908.

This invention relates to improvements in apparatus for expelling or discharging ashes, ballast water, bilge water and other mate'- rails from ships and other places of the type in which the ashes and clinker are crushed and then passed into the interior space of a mechanically driven cook or valve or into the space or port in a piston reciprocating in a cylinder from which they are discharged into the sea by fluid pressure.

Now the present invention has for its object to arrange for the discharge-of ashes and clinker from the mechanically driven valvular device by hydraulic means and to this end a pump, preferably a centrifugal pump is connected between the said valvular device and the sea as will be hereinafter described and particularly pointed out in the claims.

In the drawings, Figure 1 is a more or less diagrammatic end elevation of a hydraulic ashes eXpeller according to the present invention and Fig. 2 is a transverse section of a revoluble hollow cock or plug adapted to be alternately filled with ashes from the hopper and to be emptied by the action of the pump.

In Fig. 1 an engine (not shown) drives a centrifugal pump 58 for discharging the ashes and cinders by means of water. In this arrangement the centrifugal pump 58 is connected by a suction pipe 59 and sluice valve, indicated diagrammatically at 60, to the sea through the ships side 61. The centrifugal pump 58 is provided with two delivery pipes, the one marked 3 fitted with a valve 103 admitting water under pressure to the inlet port 9 Fig. 2 in the casing Z) of the hollow revoluble cook a, which latter has a port 52 adapted to register once in each revolution with the port 9. A second and larger delivery pipe 62 from the pump Serial No. 526,818.

the plug in the casing Z). It is evident that if desired an ordinary reciprocating or other suitable pump may be employed, in lieu of a centrifugal pump, to supply water at the necessary pressure to force the ashes or the like down the discharge pipe 64. The centrifugal pump is driven from a suitable source of power and the plug a and any suitable crusher contained in the casing z are conveniently driven by chain and sprocket wheels from the same source.

Referring to Fig. 2 it will be seen that every time the port 52 comes opposite the port 9, the large discharge port 13 is opposite the discharge opening 14. If therefore the cock 103 be opened the ashes will be wetted and dislodged by the water delivered by the pipe 3. Itis evident however that the valve 103 need not of necessity be opened. The ashes falling from the plug a are sucked downward by the strong flow from the pipe 62 and are conveyed thereby and discharged into the sea.

What I claim as my invention anddesire to secure by Letters Patent is 1. Apparatus for discharging ashes and other matters from ships and other places comprising in combination, a receptacle, a discharge duct, a hollow movable body be tween said receptacle and said duct and Patented July 5, 1910.

operative to alternately receive matter from 7 said receptacle and transfer it to said discharge duct, and a liquid impeller connected upon one side with the sea and on the other side with said discharge connection.

2. Apparatus for discharging ashes and other matter from ships and other places comprising in combination, a receptacle, a discharge duct, a hollow revoluble body between said receptacle and said duct and operative to alternately receive matter from said receptacle and transfer it to said discharge duct, and a centrifugal pump connected upon one side with the sea and on the other side with said discharge duct.

3. Apparatus for discharging ashes and other matter from ships and other places coinprislng in combination, a receptacle, a

discharge duct, a hollow revoluble body between said receptacle and said duct and operative toalt'ernately receive matter from 7. said receptacle and transfer it to, said discharge duct, a centrifugal pump connected upon one side with the sea and on the other side withsaid discharge duct, and a' delivery pipe from said pump connected with an inlet port in the casing of said hollow body, the last named having a port adapted to register withsaid inlet port in the disi charging position of said hollow body, substantially as set forth.

4. Apparatus for discharging ashes and otherrmatter from ships and other places a comprising in combination, a receptacle, a discharge duct, a hollow revoluble body be 7 2Q,
